We had choice of either Edelbrock Performer RPM or Mopar Performance aluminum cylinder heads. Both feature 84cc combustion chambers, 210cc intake/70cc exhaust ports, 2.140 inch intake/1.810 inch exhaust valves, and valve springs that support up to .600 inch of valve lift. Since we only had time to dyno one set of heads, we opted for the Edelbrocks.  The heads were test fitted and checked for both piston-to-chamber quench and piston-to-valve clearance. Piston to quench (factoring in the MLS head gaskets) checked at 0.075 inch. Valve clearance was 0.250 inch intake and 0.270 inch exhaust.
